Toall whom it may concern:

Be it known that we, REUBEN BROOKS, of Rockport, in the county of `Essexand State of Massachusetts, and OSCAR E. WAIT, of Woonsocket, in thecounty of Providence and State of Rhode Island,have invented certain newand useful Improvements in a Machine for Scoring Bobbins, of which thefollowing is a specification.

Our machine is designed for use in scoring the bobbins patented to OscarE. Wait, above named, December 17, 1878, No. 210,977.

In the accompanying drawings, Figure 1 is a plan view of a machine forscoring bobbins which embodies our invention. Fig` 2 is a transversevertical section of the same, taken on line fo w of Fig.1, as viewedfrom the right. Fig. 3 is a transverse vertical section of apart of saidmachine, taken on the line y y of Fig. l, zo 'as viewed from the left.Fig. 4 is a detached view, showing the longitudinal movement of thelive-spindles, the parts being viewed downward and a little obliquelyfrom the front. Fig. 5 is alike view of the same viewed ob- 2 5 liquelydownward from the rear. Fig. 6 is a front elevation of certain cams foracting upon the small end of the bobbin and the dead-spindles. Fig. 7 isa rear elevation of the same parts together with the frame, to whichsaid 3o cams and others are secured. Fig. S is' a side elevation, on anenlarged scale, of one of the cams or guides for acting upon the sidesofthe bobbin-barrel. Fig. 9 is an enlarged view of one of thespindle-bearings and part of the ro- 3 5 tary head which .carries thesame. Fig. 1() is a side view of a bobbin as scored by our machine. Fig.ll is a plan view of the machine upon a larger scale thanFig. 1, andFig. 12 is a front elevation of the same.

The form of the machine very much resembles an ordinary lathe, andconsists of a bed with head and tail blocks mounted thereon. We willdesignate A as the head-block because it carries the live-spindles, andB as the tail-block which carries the dead-spindles.

In the tail-block B there isa central spindle or shaft, C, which carriesa series of revolving cutters, a c," on the end thereof and between thehead and' tail block. This shaft and its 5o cutters are designed to beconnected to any proper drivin g-pulley by means of a belt running overthe pulley bg In both the head and the tail blocks there i a rotary headbearing spindles, those in the rotary head D of the head-block A beinglive-spindles, c o c, driven by planet-wheels "d d d, and those in thehead ot' the tail-block being dead-spindles e e e. The rotary head ofthe tail-block is mounted on a hollow shaftor hub, f, through which thespindle C passes. and the gear g is rigidly se- 6o cured to said hub,so` as to move with it and the rotary head.` The heath-'D is alsocarried on a hollow shaft or hub, i;,to which the gear i is attached,said hub being mounted upon a stationary shaft in axialline with thespindle C. Upon this stationary shaft there is a stationary wheel, 7c,about which the planet-wheels d d ol revolve, and into which they mesh.

Upon the rear of the machine7 and extending from end to end, there is ashaft, E, which is 7o driven `slowly by means of a worm-gear connectionwith the transverse shaftF. This shaft E is provided with gears Zm,which respectively mesh into and drive the gears g t. The spindles inboth heads are arranged to move longitudinally, and at their confrontingends to move radially in the heads. They are supported at one end by thegear-wheels g i, through which they pass, and at the opposite ends by aradially-slotted disk or head D', only one of 8o Which is shown, and ineach case the frame of the tail-block is bored out to form a bearing forthe edge of the slotted disk or head, as shown in Figs. 2y and 9, theslotted disks in each head being alike. In the head D the spindles c o c8 5 pass through bearings or boxes n., which are forced inward towardthe axis about which they revolve by a spring, o, Fig. 9. The portionsof the spindles e e e which liein the radial slots of the head aremerely enlarged Iand squared, 9o a like' spring bearing upon saidsquared portionto force them in the same direction as the boxes n of thehead D.

Springs p upon the spindles have a constant tendency to force thespindles endwise toward the head-block, and the stationary side cam, q,Figs. 6 and 12, forces them in the opposite direction against saidspring. The inner ends of said spindles c are provided with a femalecenter suitable to receivethe small end` of a roo bobbin-barrel. i

The planet-wheels d d d are so fitted tothe spindles c, by means of aspline or its equivalent, that the spindles maymove longitudinally insaid Wheels, while at the same time a rotary movement of said spindleswith the wheels is necessitated. The heads of these spindles areprovided with male centers adapted to fill and it into the borein thehead end of the bobbin, and by the side of said male centers there aresmall spurs which enter the bobbin and cause it to rotate with saidspindles.

Springs 1' on they spindles c have a constant tendency to force themtoward the stationary cam s, which acts upon the tails of said spindlesto force them toward the tail-block. Aportion, u, Vof the face of saidcam is made spring-actuated by being detached from the rest of this camand mounted upon a sliding rod in the spring box c, which contains aspring, as shown in Fig. 5, said spring being strong' enough to overcomethe power of the springs r, and acting to force the spindles in theopposite direction. A stop, w, Figs. 4, 5, and l1, limits the motion ofthis spring-actuated portion u. A guard, z, on the head-block acts.against a portion of the heads of the spindle @and prevents thespring-actuated portion from moving the vspindles until they pass bysaid guard.

At each end of the series of cutters a a there are two stationary camsor guides, 2 2, one of which isshown in side elevation by Fig. 8.

Its fellow cam is mounted upon the block G with the side cam, q, Fig. 6,and this block is held in position on its frame by a screw, 3, Fig. 7,which passes through a longitudinal slot, whereby said block audits camsmay be adjusted to bobbins of different lengths.

A suitable hopper may, if desired, be placed over the cams 2 2, so as todeposit the bobbins automatically thereon, in which case the bobbinswill be stacked one above the other and the bottom bobbin taken outsuccessively as in taking similar articles from hoppers in other andordinary machines. The bobbins are rst prepared ready for scoring in anyordinary manner. They are held one at a time either by hand or in thebottom of a hopper with the respective ends of their barrel-s restingupon the upper side of the stationary cams or guides 2 2, and just alittle back of the summit of the cutters, and with the head of thebobbin toward the head-block. The cutters are given a rapid rotarymotion, and a slow motion is imparted to the shaft F, thereby causingthe heads to revolve in such a direction as to bring the top of theheads to the front. The tail of the spindle, which first comes up in therear, strikes the cam s and is moved forward until its front end isprevented from further movement by contact with the guard z. At thistime the tail of the spindle is on the springactuated portion u of saidcam, and as the cam cannot, by reason of the guard, move the spindle,the spindle moves the spring-actuated portion of the cam backwardagainst its spring into the position represented in Fig. 4.. Just aboutthis time the head of the spindle disengages the guard z, and thespring-actuated portion ofthe cam springs forward, carrying the spindlewith it into the positionrepresented in Fig. 5. In makingthis suddenlongitudinal movement the male center and spur of the spindle engage thebobbin previously placed in proper position in the predetermined path ofsaid spindle'. At or about the same time one of the spindles c of thetail block is liberated from the upper end of the side cam q, and underthe action of spring p it also snaps suddenly toward the bobbin, toengage the small end of its barrel in thc female center of said spindle,whereby both ends of the bobbin are grasped and centered.l The springs ohave a tendency to hold the sides of the bobbin-barrel against the camsor guides 2 2 as the bobbin is carried on withthe heads. When the bobbinreaches the summit of the cutters the cams have raised it gradually, soas to clear said cutters until it rides over the rst projection andfalls on the upper and rst concentric face or guide on the edge of thecam 2, (see Fig. 8,) in which the broken circle represents the positionof the bobbin-barrel.

The size of the cams or guides 2 2 is such that when the bobbin-barrelrests upon the concentric faces the cutters will cut into the side ofthe barrel to the required dept-h. The heads pass on, carrying thebobbin around, and, by the mechanism before described, also rotating thebobbin on its own axis and moving it endwise, thereby scoring the bobbinnot only around its barrel, but around it in a spiral direction, thepitch of the spiral being determined by the incline of the cam s. Themiddle forward projection between the two concentric faces of the camsagain lifts the bobbin out of the reach of the cutters, thereby leavingthe plain, unscored, longitudinal surface 4, Fig. l0; but upon passingsaid projection the cutters again act as before, after which a thirdprojection disengages them. The tail end of the spindle c just aboutthis time jumps the shoulder of the cam s, (which shoulder is upon theunder side and not shown,) thereby suddenly withdrawing the spindle fromthe bobbin. At the same time the side cam, q, begins to act to withdrawthe spindle e, so that the bobbin is released and falls from themachine. The relative size of the planet-wheels and gear which rotatethe spindles c c c upon their own axis is such as to impart to thebobbin about one revolution on its own axis in making that part of arevolution about the cutters that is required to carry the bobbin overboth the concentric faces and immediately connected projections of thecams 2 2. After the spindles drop the bobbin they go on upward andforward to take another bobbin, and proceed as before described. All ofthe spindles in each set operate in like manner.

From the foregoing it will be seen that our machine has the followingleading characteristics, viz: The pitch of the scores in thebobbin-barrel is determined by the relative longitudinal movement of thebobbin and cutters. The alternate scored and longitudinal plane IOO IIO

surfaces of the bobbin are caused by the relative movement of the bobbinand cutters to and from each other under the action ot' springs and camsor guides having concentric faces, divided by projections or swells.There are other characteristics peculiar to our machine, but these whichwe have thus partieularized might be embodied in a machine verydifferent in form from ours, but in fact so as to contain much of thesame mechanism, as for instance, a machine with only one pair ofspindles, which may be moved longitudinally by means of cams andsprings, the live-spindle rotating only upon its own axis, in which casethe cam for imparting this endwise motion would rotate with thelive-spindle and act against a stationary pin. rIhe series of cutterswould be placed on a spring -actuated and swinging frame by the side ofsaid spindles, and the revolving cutters moved to and from the bobbin byan arm acted upon by a cam on the live spindle, said cam having theconcentric faces with elevations between to produce the scored andunscored longitudinal surface on thebobbin-barrel, as hereinbeforedescribed.

We are aware that various combinations of spindles, cutters, cams, andsprings have heretofore been used, and also shown in prior patents, forcutting screw-threads, for making wooden shoes for turning articles ofwood, and for various other purposes, none of which are claimed by us;but so far as we know we are the iirst to invent machinery ot' any kindtor automatically scoring bobbin-barrels, and more especially we are thefirst to invent machinery for automatically scoring the same in whichthe cutter has an intermittent action, so as to leave a plain surfaceextending longitudinall y over the bobbin-barrel, and with a scoredsurface upon either side of said plain surface; neither do we know ot'any prior machine which can possibly be used for said purpose withoutmaterial modification.
